To @ZZ whom it may concern:

Be it known that ll, Janne J. HAROLD, a eitizenpf the United States ofnliirnerica, re siding at Jersey City, in the county of Hudson and Stateof New Jersey, have invented certain new and useful improvements inMetal Filing, of' which the following is a specilication, referencebeing had therein to the acompanying drawings.

My' invention relatesl to improvements in metallic piling as used insubway, foundation, and irrigation work, dams', mine-shafts, caissons,sea-Walls, locks, coffer-dams, retaining-walls, and similar structures,`and comprises anged beams, preferably of the channel-beam or ll-beamtype, provided with irlterlocking members. 4

Referring to the accompanying drawings, Figure 1 is an end view of a runof showing the interlocking members back to back and locking the flangesof libeams, Fig. 2 is another end view showing the same interlockingmembers with U- shaped back fastened face to face and also locking theflanges of I-beams. Eig. 3 is an end viewv of a run of lmy piling,showing the use of channel-beams and the interlocking l1 members shownin Fig. 2 with one end cut o. Fig. L1 shows another method of fasteningthe interlocking members shown in Fig. 3, so that the fastening-boltsare at right angles to the channel-beams instead of parallel with thepiling, as in Fig. 3. Eig. 5 shows a combination arran ement of Figs. 1and 2, and Eig. 6 a comination arrangement of Figs. 3 and 4.

A represents the -beams. channel-beams, and B, B', and lookin members. l

ln *igl 1 the C represents the B2 the inter* interlocking members arepiling fastened,

b'aek so that when formed with a straight bolt E or other suitfastenedtogether by a ada ted to receive the flanges on one side of an l-beam. iy

In Fig. 2 the back of each interlocking member is FSJ-shaped, and theflat surfaces are fastened in Fig. 1, so that the flanges on one side ofeach li-beam may be engaged and retained by one ofthe jaws of each ofthe interlocking members.

One side of the interlocking members E ma' and the fiat surfaces may inthe usual way, as shown in Eig. 4, or by bendin the flat surface aroundbeneath the charme as shown in Fig. 3.. Where a com bination of theinterlocking members is employed the back of the members B and B2 arepreferabl longer, as shown in Figs. 5 and 6, so as to a low encu h roomfor the other interlocking members E and l).

Modifications may be made without departing from the spirit of theinvention.

Having described my invention, what 1 claim, and desire to secure byLetters Patent,

In metal piling, interlockin members and flanged beams, said interlocing members provided with channels and flat surfaces said flat surfacesof said members fastene l. together and said channels ada ted to enlgage and retain the lian es of sai beams.
